Need help identifying a 40 circuit 200 amp service panel manufacturer.
No manufacturer's label.

The only identification features on the breaker panel are.
Cat No: MP 4020

Sorry, not thinking.
Looks like a Siemens WP box.

The THQP GE twin breakers in that panel only fit GE panels because of their design, that panel is full of them.
